Truth is one; the sages call it by many names
Joseph Campbell: Unnameable. Unnameable. It is transcendent of all names.
Bill Moyers: God?
Joseph Campbell: “God” is an ambiguous word in our language because it appears to refer to something that is known. But the transcendent is unknowable and unknown. God is transcendent, finally, of anything like the name “God”. God is beyond names and forms. Meister Eckhart said that the ultimate and highest leave-taking is leaving God for God, leaving your notion of God for an experience of that which transcends all notions.
The mystery of life is beyond all human conception. Everything we know is within the terminology of the concepts of being and not being, many and single, true and untrue (…) We want to think about God. God is a thought. God is a name. God is an idea. But its reference is to something that transcends all thinking. The ultimate mystery of being is beyond all categories of thought. As Kant said, the thing in itself is no thing. It transcends thingness, it goes past anything that could be thought. The best things can’t be told because they transcend thought. The second best are misunderstood, because those are the thoughts that are supposed to refer to that which can’t be thought about. The third best are what we talk about. And myth is that field of reference to what is absolutely transcendent.”
